Answer:
Step-by-step explanation:
<u>According to data in the table we see pairs of points:</u>
<u>This gives us the rate of change:</u>
- (125 - 75)/(5 - 3) = 50/2 = 25
<u>The y - intercept is zero:</u>
- 75 = 3*25 + b
- 75 = 75 + b
- b = 0
<u>The line is:</u>
This is the line on the graph B
<u>Note.</u> <em>Its not clear what is needed regarding the table on the bottom</em>
Answer:
<h2>A. the slope is 8.</h2><h2>A. the y-intercept is 1</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
y = mx + b
m - slope
b - y-intercept
We have the equation y = 8x + 1.
Therefore:
m = 8, b = 1
Answer:
$28
Step-by-step explanation:
Time = 4 hours
Charge = $7 / hour
Multiply those two numbers:
4 hour × $7 / hour = $28
Function f(time) = $7 × time
Hopefully this answer helps you :)
Answer:
A) CUB
Step-by-step explanation:
Of the suggested planes, only CUB contains both points C and T.
___
<em>Comments on the other answer choices</em>
BED contains point T, but not C
ACE contains point C, but not T
ABE contains neither C nor T
To check if a relation is a function, given a mapping diagram of the relation, use the following criterion: If each input has only one line connected to it, then the outputs are a function of the inputs.
